I will also save you from all your uncleannesses: and I will call for the {o} grain, and will increase it, and lay no famine upon you.

(o) Under the abundance of temporal benefits he concludes the spiritual graces.

Wesley's Notes

36:29 I will also save you - I will continue to save you. From all your uncleannesses - Salvation from all uncleannessess, includes justification, entire sanctification, and meetness for glory. The corn - All necessaries comprised in one.

Jamieson-Fausset-Brown Bible Commentary

29. save . from all . uncleannesses-the province of Jesus, according to the signification of His name (Mt 1:21). To be specially exercised in behalf of the Jews in the latter days (Ro 11:26).

call for . corn-as a master "calls for" a servant; all the powers and productions of nature are the servants of Jehovah (Ps 105:16; Mt 8:8, 9). Compare as to the subordination of all the intermediate agents to the Great First Cause, who will give "corn" and all good things to His people, Ho 2:21, 22; Zec 8:12.

Matthew Henry's Concise Commentary

36:25-38 Water is an emblem of the cleansing our polluted souls from sin. But no water can do more than take away the filth of the flesh. Water seems in general the sacramental sign of the sanctifying influences of the Holy Ghost; yet this is always connected with the atoning blood of Christ. When the latter is applied by faith to the conscience, to cleanse it from evil works, the former is always applied to the powers of the soul, to purify it from the pollution of sin. All that have an interest in the new covenant, have a new heart and a new spirit, in order to their walking in newness of life. God would give a heart of flesh, a soft and tender heart, complying with his holy will. Renewing grace works as great a change in the soul, as the turning a dead stone into living flesh. God will put his Spirit within, as a Teacher, Guide, and Sanctifier. The promise of God's grace to fit us for our duty, should quicken our constant care and endeavour to do our duty. These are promises to be pleaded by, and will be fulfilled to, all true believers in every age.
